"The original bug was a complaint that _mm_srli_si128 mis-compiled when passed
a constant vector ("{0x123, 0x456}" syntax). The fix is to simplify the
_mm_srli_si128 macro, and move the "* 8" from the macro into the compiler
back-end. I can't change the existing __builtins because so many people are
using them :-(."
Patch by Stuart Hastings!
